The "real solution" in preventing recurrence of another Sujit Wilson-like incident lies in the closure of all open borewells and right now this was the focus area, a senior Tamil Nadu government official said on Wednesday.

Wilson, who fell into a disused borewell at Manapparai near Tiruchirappally on October 25, was pulled out dead by rescuers early on Tuesday, after a futile 80-hour struggle to save him. Commissioner of Revenue Administration J Radhakrishnan said the rescue operations were done "professionally" but that the result was "negative."

Addressing a press meet here, he said all efforts possible were taken in good coordination with various agencies to save the two-year old boy.

The rescue efforts were "done professionally, but unfortunately there was a negative result," he said.

"The real solution (to prevent recurrence) is all unused borewells should be closed or be converted into rain water harvesting structures. Chief Minister (K Palaniswami) has directed all district collectors (in this connection)," he said.

"Open borewells should be closed...That is our focus area," he said, adding various Government departments were on the job.

While the 80-hour long operations failed to rescue the boy alive, the rescuers retrieved his body in lines with the Centre's management of dead guidelines, he said.

Radhakrishnan, who oversaw the rescue operations at the mishap site in Nadukkatupatti, had on Tuesday said the body of Wilson was in a "highly decomposed" state and "dismembered" before it was pulled out from a depth of around 88 ft.
